Theslot 9 injthe arm 10 alsoreceives a fulcrum pin 9 sothat; as thearm 10 is vibrated by reason of its engagement with thercrank pin 19, can-also slide-onv the fulcrum pin. 9- andthus permit the dog 7 in its reciprocation to-ifollow a the wincllned plane of the: guide This plane is .al'so'i'n'clined in respectto that of the: stavesupporting flanges 6, so' that when the dog 7' first. acts upon therear "end of. a stave it. will be'adjacent tothe inner? faceofathe stave and will thereforebe .free'from liability to engage anybut the lowermost-- stave, but as; it pushesthe stave forward its acting end will also rise on the end of the stave, and its hold upon the same will therefore be increased.

As the dog is projected it will push the stave ahead of it and. between a pair of transverse bilging bridges, the lowermost of which is represented at 11 in Figs. 2 and '3, and-the uppermost at 12 and 12 in Fig. 3,

the member 12 of the upper bridge being fixed in position and the member 12 being held in its proper relation to the member 12 by means of removable locking bolts 12*, so that it can be readily withdrawn when, for any reason, itis desirable to gain access to a stave which has been thrust between .the bilging bridges. Said bridges are, as shown in Fig. 3, continuous from end to end, and those faces of the bridges which act upon the stave are, as shown in Figs. 2 and 3, curved both transversely and longitudinally so as to impart the proper transverse and longitudinal bilge to a flat stave thrust longitudinally between them. 7

The upper and lower bilging bridges have their adjoining faces slotted transversely, as shownat 13, in Fig. 3, and by dotted lines in Fig. 2, for the reception and shedding of anumber of pairs of wires 14 (four in the present instance) which are drawn from reels mounted so as to be free to turn on stationary bearings at one end of the ma-- chine, these wires are manipulated as herein after set forth so as to form the sheds for the reception of the successive staves and so as to be crossed between successive staves of the set and have a plurality of twists imparted to them between the terminal staves of successive sets. u

Mounted in suitable bearings upon a longitudinally inclined transverse table 15 of the machine frame is a tubular shaft 16 which has a half turn imparted to it after each stave insertion, said half turns being first in one directionand then in the opposite direction, and, at certain intervals, the shaft has a plurality of movements of full rotation, such movements being eflected by means of gearing illustrated in Fig. 4, on reference to which it will be observed that there'is a shaft 16 for each pair of wires and that these shafts are geared together by means of intermeshing spur wheels 17 so as to operate in unison.

Mounted so as to be free to turn on one of the shafts 16 are a pair of bevel wheels 18 and 19, .both of which are in mesh with a bevel pinion 20 on a shaft 21 which is mounted so as to be free 'to turn in a bearing on the table 15 and is in line longitudinally with another shaft 22 likewise mo unted and to which it can be clutched when desired by one face of a shifting clutch sleeve 2.3,the latter being under control of a piv- *"otedlever .24 which canbe moved in one direction by means of a spring 25 and in whenever rotative movement is imparted to the shaft 21 and either of said bevel wheels may, by means of a clutch sleeve 28 (Fig. 4) be clutched to the shaft 16 011 which it is mounted. The sleeve 28 is controlled by a lever 29 (Fig. 2) pivotally mounted on the table 15 and having movement imparted to it-from a cam 30 011 the shaft 5 through the medium of a reciprocated rod 31. The clutch sleeve 23, when in the position shown in Fig. 4, serves to connect the shaft 20 directly to the shaft 22, but said shafts may also be connected indirectly, through the medium of intermeshing spur wheels 32, 33, 34 and 35, when the clutch sleeve is moved into engagement with a clutch face on said spur wheel 35, the character of the spur wheels 33, 34 and 35 being such that when the shaft 21 is thus driven it will rotate a plurality of times for each rotation of the shaft 22. I

As shown in Figs. 6 and 7 the inner end of eaehof the shafts 16 has a head '36, to the ends of which are pivoted jaws 37, the head also having mounted thereon guide rollers 38 for the wires 14, the latter passing through openings in the jaws 37, thence over the rolls 38, thence between the outer face of the shaft 16 and a longitudinally movable slide 39 thereon, thence between the beveled inner face of said slide and the corresponding beveled outer face of a block 40 on the shaft, and thence through openings 41 to the interior of said shaft.

The jaws 37 may be caused to swing outwardly by the action thereon of a head 42 on a rod 43 disposed within the shaft 16 and having an internal head 44 through which and through longitudinal slots 45 in the shaft 16 passes a transverse pin 46 which engages with the slide 39. The slide 39 is provided with a groove 39 for the reception of pins projecting from a fork 47 on a transverse roek shaft 48 (see Fig. 2) so that when said shaft 48 is rocked in one direction the jaws 37 will be expanded, as shown in Fig. 7, and the wires will be released from confinement between the block 40 and slide 39 and hence will be relieved from tension, but when said shaft 48 is rocked in the opposite direction the jaws 37' will be permitted to contract, as shown in Fig. 6 and the wires will be clamped between the block 40 and slide 39 so as to be subjected to tension.

When the jaws 37 are closed, as in Figs. 2 and 6, they are prevented from opening by reason of the contact therewith of fingers o0 (Fig. 3) projecting from upper and lower resser bars 51 and 51 which are pivotally mounted, respectively, upon arms 52 and 52%,the arms 52'beingcarried anup nism"for pressi lig' and felea sing the clamb} per rock shaft. 53 andtheiarms 52f3being plate 68. has itsopenation'fjarrested:at t carried by loweri rock shafts 53? wvlnch are interva s-bymean fie am 87 "(F gl l operated: from the shaft 53. by ineansjofinthe shafts; said cam a' ingnponj abarBB an arm {58011 theiupper'rock shaft 53'; v

v A crank pin'103 acts upon a rack bar 104 whose ra'ck; through the medium of a suitable pinion, imparts back and forth movement to a shaft 105 mounted so as to be free to rock back and forth upon theshaft '22,'said'shaft 105-being connected, as shown in Fig. 4:, to a disk 106 which, as shown in Fig. 20, carries spring pawls 107 engaging lwithteeth on a disk 1 08 which is secured to the shaft The disk 106 is therefore rocked back and forth on each rotation of theshaft' 4, but only the forward movements ofsaid disk are transmitted to the shaft 22, ili'e pawls 107 on the backward movement of the disk slipping over the disk 108 without imparting any movement'thereto- When the clutch- 23 is shifted from engagement with the clutch member on the shaft 21 to that 'on-thehub of the spur wheel 35, in order to increase the number of rotation-s imparted l'lOi the shafts 16,' a sudden strain is exerted upon the crank arm 109and in order to relieve the strain ina measure said crank arm'is free to yield under the pressure of the springs 110'. i "The lower bilging bridge 11 occupies a fixed vertical position and the upper bilging bridge is retained in fixed vertical position in respect to thelower bridge by means of studs 111 interposed between the member 12- of saidupper bridge and the top member 112 of the fixed frame of the machine, the studs 111 being, by preference, adjustable as to length so as to vary the space between the upper and lower bilging bridges to accord with-the different thicknesses of staves which may be employed.

In preparing the machine for operation the series of pairs of wires 1 1 are drawn from the reels at the rear of the machine first through the rear ends of the hollow shafts 16, then through the openings 41 in said shafts, then between the tension blocks and slides 89, thence through the guide openings in the jaws 37, and thence to a suitable starting point where they can be retained until the first stave has been inserted into the open shed of wires.

--?The stave rack being filled with staves, as shown in Fig. 3, the machine operates as follows: the jaws 37 being held open, as shown in Fig. 7, the bottom stave of the pile is thrust into the openshed of wires by the forward motion of the pusher head 7, the stave being at the same time bilged longitudinally and transversely between the upper and lower bilging bridges. The jaws 37 'are then closed and held in the closed position-by the presser bars 51, tension is imparted to the wires, and the shafts 16 have a half turn imparted to them so as to cross the wires behind the inserted stave. The bound stave is then pushed forwardly by the swinging dogs 70, the plate 68 at this time being free from pressure so as not to interfere with the introduction of the stave between said plate and the supporting bar 69 below it. New sheds of wires being then formed, a second stave is inserted into the same by the action of the pusher head 7, and said fresh stave is driven ahead by the swinging dogs 70 under the action of the projecting member 71 of the cam 71 so as to move both staves forwardly. As soon as the forward stave is gripped between the clamps 68 and 69, the projecting member 71" of the cam 71 causes the dog 70 to jam the forward edge of the last insertedstave against the rear edge of the previously inserted stave and embed the crossed wires in the meeting edges of the staves. The wires are then again crossed behind the newly inserted stave and the operations are repeated until the desired number of staves have been bound together. At intervals, between stave insertions, the clutch member 28 is shifted between the bevel wheels 18 and 19 so that the direction of twist of the wires 14 will be reversed in order to prevent the incoming runs of wire from becoming twisted around one another.

After the final stave of a set has been inserted the clutch 23 is shifted so as to transmit motion from the shaft 22 to the shaft 21 through the medium of the multiplying gears 85, 3i, 33, and 32 whereby, on the operation of the shaft 22, there will be a plurality of rotations of the shaft'2l and a consequent plurality of rotations of the hollow shafts 36 and a plurality of twists imparted to the various pairs of wires.

The last staves of the bound set being relieved from the pressure of the plate 68, through the action of the cam 87, the first stave of the new set is then inserted into the open sheds of wires, and, when said new stave is pushed forwardly by the dogs 70, it will, through the medium of the preceding twisted wires, push the series of bound staves ahead of it forward without any tendency to jam the twists together. As soon as the first stave has been pushed forward, the action of the plate 68 is again restored until the first stave of the next set is in readiness to be inserted.

When the twisted wires between the terminal staves of successive sets have reached a position between the knives 81 the knife bars are caused to approach each. other and said knives sever the twisted wires about the middle of their length so as to leave a plurality of twisted wires not only in the rear of the set which has already been bound but also in'advance of the'set which isbeing bound, thereby 'prevei'iting the terminal the set of sta-vesis' bein' dled and setup -n1toba=r1e lVe cla m:
